Berk 3″ High-Flow Catalytic Converter – Nissan 240SX / Skyline GTR
More flow, zero stink. This USA-made 3″ Berk High-Flow Cat moves exhaust 87 % as freely as a straight test pipe—double the OEM converter—while keeping your cabin and the street free of raw-fuel odor.
Why Choose Berk’s HFC?

- True 3″ through-bore – no neck-downs in tubing or flanges for maximum flow.
- 304 stainless construction – tube, flanges, and welds shrug off rust and track heat.
- Bolt-on convenience – includes multilayer steel gaskets and zinc-plated hardware.
- Street friendly – catalytic efficiency without the rotten-egg smell.
- Made in the USA • EPA-approved*
